ignore: remove .hgignore from ignore list if nonexistent

Previously we would always pass the root .hgignore path to the ignore parser.
The parser then had to be aware that the first path was special, and not warn if
it didn't exist.

In preparation for making the ignore file parser more generically usable, let's
make the parse logic not aware of this special case, and instead just not pass
the root .hgignore in if it doesn't exist.

import os

if os.environ.get('COVERAGE_PROCESS_START'):
    try:
        import coverage
        import random

        # uuid is better, but not available in Python 2.4.
        covpath = os.path.join(os.environ['COVERAGE_DIR'],
                               'cov.%s' % random.randrange(0, 1000000000000))
        cov = coverage.coverage(data_file=covpath, auto_data=True)
        cov._warn_no_data = False
        cov._warn_unimported_source = False
        cov.start()
